137. Sterola conspicua n.sp. 
2 dull shining black, the legs and scape of antenne brown, antenne 
outwardly infuscate. 
Head and thorax to the propodeum with a microscopically fine and 
delicate reticulate surface sculpture; finely, shallowly and fairly closely punc- 
tate, and hairy. Head wider than the thorax, nearly as wide as long, width 
between the eyes greater by a half than the length from eye to vertex; 
flatly convex above, depressed in front, a little temid beneath: vertical mar- 
gin straight, temples rounded, eyes convex; antennz reaching the mesoscu- 
tum, all the segments considerably longer than wide, antennal fosse deep; 
clypeus carinate, apically depressed and projecting slightly in front of the 
anterior margin of the head, which is angulate, not transverse, sloping at 
the sides, the carina extending backward shortly on the top of the head; 
mandibles stout, curved, concavo-convex, truncate apically and toothed, base 
not quite reaching the eye: gula and sides of the head convex, the former 
medially foreshortened, wider than long, anterior margin arcuately concave, 
posterior margin incised; propodeum very finely rugulose; abdomen a little 
depressed, ovate, smooth and polished; wings subinfuscate, with a faint 
yellowish brown pigmentation; length 2.25 mms.

not quite reaching the eye: gula and sides of the head flatly convex, the 
former medially foreshortened, wider than long, slightly depressed along the
